CLOSURE FOR OIL-CANS.

SPECIFICATION forming part Of Letters Patent NO. 614,035, dated November 8, 1898.

Application filed A t 16, 1897. serial No. 648,481. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE STOCKTON, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Closures for Oil-Cans and I do hereby declare the following to be a full, clear, and exact description of said invention, such as will enable others skilled in the art to which it most nearly appertains to make, use, and practice the same.

This invention relates to improvements in closures for liquid-packing cases, and more particularly to closures for oil-packing receptacles; and it consists in the novel arrangement and construction of the parts, as hereinafter more fully set forth.

In the drawings, Figure 1 is a sectional view of a packing-case having this invention applied thereto, the body of the case being cut away to show only that portion to which the invention is directly connected. Fig. 2 is a plan view of the invention as seen from above.

Heretofore the packages or cans in which oil has been carried for transportation have been provided with pouring-spouts and closures therefor which have of necessity been so constructed as to be raised considerably above the top of the can, it being necessary to have the upward extension in order that the closure for the same would operate. This form of construction has been objectionable in that the crating-space within which the various cans have been packed for transshipment has been necessarily limited and has been by this former construction encroached upon. Further, the crates themselves have been necessarily constructed with more lumber than would be employed if the body of the can alone were to be taken into consideration. To overcome these several objections is the object of this invention.

The object set forth is herein accomplished by constructing the spout A and screw-head B in as fiat a form as possible to obtain the desired effect, the height of the screw-head B being governed entirely by the necessary altitude of the spout A, which can be just sufficient to clear the curled construction of the edge of the can. The spout A and screwhead B are both secured to the disk C, which it is designed should be securely fastened to the top of the can X by the usual means of soldering the edge of thesaid disk to the top of the can after fitting it upon an aperture provided'in the can for the introduction of the lower parts of the closure.

The screw-head B has rigidly attached there to the screw B, which is provided with an inverted-cup-shaped collar 13 the edges of which are turned toward the inside of the body of the can. The threaded perforation is extended through the cap D and the boss D, which is secured in the center of the said cap.

It will be observed that as the collar B and the screw-head B are both secured to the barrel of the screw B it will not be extended or change its position relatively to the disk C. This will have the effect upon the cap D, provided the same is prevented from rotating, of drawing the same upward or lowering it. The disk D is prevented from rotating by means of the guide extension E, which is secured firmly to the under side of the disk C and extends downward into the cut-away portion or niche D in the edge of the cap D. The end E of the said extension is turned inward, so that when in position it will prevent the downward movement of the cap D out of engagement with the screw B.

The cap D regulates the passage from the body of the can X to the spout A, which is closed while the cap D is raised, and when it is lowered the said passage is closed. This passage is formed by the ridge C, which is struck down from the disk C and against which the pad of cork F, which rests on top of the cap D, is drawn. The passage mentioned is closed for the reason that the spout A opens within the circle of the ridge 0', and when the pad F is drawn against the said ridge the communication between the said spout and the body of the can is out 01f.

The cup-shaped collar B is provided for the purpose of preventing the seeping through the screw-threads in the screw B and boss D of the oil into the space inside of the ridge 0 after the cap D is drawn upward against the said ridge. It is for this purpose that the downward edge of the said collar is brought to the same plane as the lower edge of the ridge C, so that as the pad F is drawn against the said ridge the edges of the collar 13 will sink into the said pad and by so doing cut 0% the communication referred to by way of the screw-threads of the screw B.

It will be obvious that if thus constructed the closure for a receptacle of the nature described will have the smallest projection or elevation of the operative parts-that is, the spout and handle for operating the closure device-ever attained, the projection of the operating device being constant at all times and limited to the height or projection of the pouring-spout. This is accomplished by constructing the parts, as herein described and shown, in such manner that the valve or closure device operates wholly within the body of the can, projecting from the under side of the head thereof.

Having thus described this invention, it is claimed:

A closure for oil-cans, consisting in the combination of a screw mounted Within the can and provided with a head extending outside the body of the can, a collar having a downwardly-turned edge and mounted rigedly on the barrel of the screw inside the body of the can, a disk provided with a central perforation to receive the threaded portion of the screw and with a soft upper surface, a guide for the said disk to prevent its rotation, a ridge extended into the body of the can surrounding the said screw and adapted to press against the upper surface of the said disk, and a pouring-spout opening into the body of the said can within the circumference of the said ridge, substantially as described.

In testimony whereof I have hereunto set my hand this 21st day of July, 1897.

GEORGE STOCKTON.
